Description

UV protecting cosmetic composition with good stability and texture using water in silicone type emulsion as a thickener}

The present invention is to increase the stability of the emulsion through the increase of the trauma during the oil-in-water type emulsifier, including water and water-soluble thickener in the silicone as a thickener to enable the use of a large amount of silicone emulsifier to help improve the feeling of use The cosmetic composition for the present invention, more specifically, in the form of blending the thickener itself, unlike the general single water-soluble thickener in the form of a water-in-oil type, that is, a water-soluble thickener and the increase in silicone trauma The water containing the agent is in water-in-oil form.

Since the water-in-oil thickener has a shape that seems to release water and a water-soluble thickener in the silicone, it does not nourish the stability of the oil-in-water formulation even when a large amount of silicone is used, and the phase is changed in the water-based emulsion formulation. A technique for increasing the viability of a traumatic wound like a gel and stabilizing a large amount of silicone in the gel matrix to remove the stiff feeling of the existing sunscreen and to enhance the feeling of use by using a breathable silicone emollient. to be.

Excessive exposure of the skin to sunlight results in skin damage and skin disorders such as scaling and skin texture changes in the stratum corneum, severe skin cancer and the like. Excessive or chronic skin exposure also promotes skin aging. In order to prevent such skin disorders, a sunscreen cosmetic composition containing a certain amount of a safe and effective UV blocker is used.

Sunscreens currently used in the cosmetics industry can be broadly divided into organic sunscreens and inorganic sunscreens. Most sunscreen products that contain organic or inorganic sunscreens absorb or reflect UV rays, and are trying to effectively block UV rays by using both of them.

The regular use of sunscreen is an essential element because the exposure to ultraviolet light is inevitable in everyday life. However, the greasy feeling by using the sunscreen and the stiff aftertaste through the use of a lot of inorganic sunscreens can be said to be difficult to feel while using the sunscreen of modern people. As a result, researchers are making great efforts to improve the control and usability, and the following methods are used as such efforts.

(a) Reduced amount of sunscreen using sunscreen booster

(b) surface modifications that encapsulate or form complexes on certain materials;

The introduction of the above process is intended to reduce the amount of the sunscreen used on the product feeling and to improve the sense of smell through the surface modification, but the situation is not enough to hide the unique feeling of the sunscreen.

No. 10-1002866 (invention name: sunscreen cosmetic composition in the form of water-in-oil emulsion), 10-0402485 (invention name: sunscreen cosmetic composition of water-in-oil emulsion formulation containing powder) Exists.

In general, emulsified cosmetic composition forms are roughly divided into oil-in-water (O / W) emulsion type and water-in-oil (W / O) emulsion type. Water-in-oil (W / O) emulsified type has excellent cosmetic persistence and water resistance, but has a disadvantage in that it imposes a burden on the skin due to stickiness, oiliness, waxiness, and poor application feeling such as spreadability and spreadability. Oil-in-water (O / W) emulsifying type has the advantage of moist feeling and soft, in the case of the above-described patent to minimize the disadvantages of the oil-in-water emulsion cosmetic composition and oil-in-water emulsion cosmetic composition, and highlight the advantages It is only a technique for improving the feeling of use by using a large amount of organic or inorganic sunscreen directly.

Therefore, in order to solve the above-mentioned problems, the present inventors can increase the stability of the emulsion and enable the use of a large amount of silicone emulsifier by increasing the trauma during the oil-in-water type emulsifier formulation, including water and water-soluble thickener in the silicone as a thickener. Even though it contains a large amount of sunscreen, it is possible to complete a cosmetic composition that has dramatically improved the feeling of use.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The present inventors earnestly researched to improve the greasy feel of the existing sunscreen cosmetic composition and the stiff aftertaste through the use of a lot of inorganic UV blockers. As a result, when the oil-in-water type sunscreen cosmetic composition contains water and a water-soluble thickener in the silicone as a thickener, a large amount of silicone can be used, and the stability of the formulation is promoted by helping to increase the trauma in the oil-in-water emulsion formulation. The present invention was completed by confirming that it helps to enhance the feeling of use.

Therefore, the present invention provides a sunscreen cosmetic composition containing a water-in-oil type thickener.

The present invention also provides a process for producing the cosmetic composition for blocking ultraviolet rays.

The present invention provides an oil-in-water type sunscreen cosmetic composition.

The present inventors earnestly researched to improve the greasy feel of the existing sunscreen cosmetic composition and the stiff aftertaste through the use of a lot of inorganic UV blockers. As a result, when the oil-in-water type sunscreen cosmetic composition contains water and a water-soluble thickener in the silicone as a thickener, a large amount of silicone can be used, and the stability of the formulation is promoted by helping to increase the trauma in the oil-in-water emulsion formulation. In addition, it confirmed that it helps to improve the feeling of use.

According to one aspect of the present invention, the present invention provides an oil-in-water type sunscreen cosmetic composition comprising:

(a) 1-10% by weight of a thickener in water-in-oil form based on the total composition; And

(b) 1-10% by weight of silicone emollient relative to the total composition.

As used herein, the term “water-in-water type” refers to an emulsion in which oil droplets are dispersed in water, and is also referred to as an o / w emulsion. A representative example is milk, mayonnaise, vanishing cream, and the like, which is a corresponding word in the following water-in-oil type.

As used herein, the term “water-in-oil type” refers to an emulsion or emulsion in which water is dispersed as fine particles in oil and is in an emulsified state.

As used herein, the term "thickener (粘 增 劑)" refers to a high molecular compound added to form the viscosity of the product, or to increase the viscosity of the product. Types of thickeners include natural polymer compounds, semisynthetic polymer compounds, and synthetic polymer compounds.

According to a preferred embodiment of the present invention, the water-in-oil type thickener is based on (a) dimethicone: 1-20% by weight relative to the whole water-in-oil type thickener; (b) cyclopentasiloxane: 1-10% by weight; (c) sodium polyacrylate: 1-30% by weight; (d) Trideces-6: 1-10% by weight; (e) Fiji / Fiji-18 / 18 dimethicone: 1-5% by weight; And (f) purified water: 10-40 wt%, most preferably (a) dimethicone: 19 wt%; (b) cyclopentasiloxane: 9% by weight; (c) sodium polyacrylate: 26% by weight; (d) Trideces-6: 6 wt%; (e) Fiji / Fiji-18 / 18 dimethicone: 1% by weight; And (f) purified water: 39% by weight.

The dimethicone used in the silicone emollient is a dimethicone which is different from the dimethicone used in the water-in-oil type thickener. The dimethicone used in the water-in-oil type thickener is used as a thickener, but is used in the silicone emollient. The dimethicone to be used is for the use of an antifoaming agent.

According to a preferred embodiment of the invention, the dimethicone as the antifoaming agent used in the silicone emollient may preferably exhibit the following properties:

(a) viscosity: 100-100,000 m 2 / s (25 ° C.); And

(b) Specific gravity: 0.80-1.30 (25 ° C.).

In the present invention, the use of the water-in-oil type thickener and the silicone emollient is a very important component to improve the greasy feel and the stiff aftertaste through many uses of the inorganic UV blocker. Because the water-in-oil type thickener has a shape that seems to release water and a water-soluble thickener in the silicone as shown in Figure 2 does not nourish the stability of the oil-in-water type formulation even when a large amount of silicone is used As the phase changes (inversion) as shown in Fig. 3 to increase the traumatic aqueous phase as a gel and to stabilize a large amount of silicon trapped in the gel matrix of the increase to remove the stiff feeling of the existing sunscreen and use the breathable silicone emollient Because it can promote.

More specifically, the water-in-oil type thickener is a blended emulsifiable thickener consisting of stirring sodium polyacrylate, purified water, Fiji / Fiji-18 / 18 dimethicone, dimethicone, cyclopentasiloxane, and trideces-6 It is a water-in-oil type containing purified water and sodium polyacrylate on silicone consisting of dimethicone, cyclopentasiloxane, trideces-6, and Fiji / Fiji-18 / 18 dimethicone. have. In the oil-in-water type emulsion formulation, sodium polyacrylate, which was dispersed in silicone during the mixed emulsification of the oil phase part and the water phase part, was phase-inverted by Trideces-6, and the water phase increased in line with the aqueous phase. The silicone, which was used to encapsulate the trauma of the thickener phase, has a mechanism of stably trapping on the aqueous phase, i.e., gel, which has been augmented by sodium polyacrylate. Indeed, in Figure 4 we can see the oil phase trapped on the gel of the water phase. By using a co-emulsifying agent such as cetearyl alcohol, which will be described later, the oil-in-water type of the oil phase is more stably maintained, and the sunscreen is effectively mixed with the sunscreen to effectively block the ultraviolet rays, and the sunscreen's rich and stiff feel It can be replaced.

According to a preferred embodiment of the present invention, the sunscreen cosmetic composition may further include the following co-emulsifier and sunscreen.

The co-emulsifier may preferably comprise 0.1-5% by weight of at least one co-emulsifier selected from the group comprising polysorbate, cetearyl alcohol, dicaprylcarbonate and behenyl alcohol, based on the total composition, More preferably 0.2-3% by weight, most preferably 0.5-2% by weight.

The sunscreen is preferably 1-20% by weight of at least one sunscreen selected from the group comprising ethylhexylmethoxycinnamate, ethoxylsalicylate, isoamyl P-methoxycinnamate, based on the total composition It may comprise, more preferably 3-18% by weight, most preferably 7-15% by weight.

According to another aspect of the present invention, the present invention provides a method for preparing an oil-in-water type sunscreen cosmetic composition comprising the following steps:

(a) uniformly dispersing purified water (the remaining amount after mixing the whole composition), 1-3% by weight of glycerin and 1-4% by weight of 1,3-butylene glycol with respect to the whole composition in the aqueous phase;

(b) uniformly mixing the thickener in water-in-oil type and the silicone emollient;
